Programmed Problem Solving
If you wanted the
surface
areas of each of
Jupiter'
s
12 moons,
you could repeat the above procedure 12 times
.
However, you
might wish to write a
program
that would calculate
area
of
a
sphere
from its
diameter,
instead of pressing all the keys for
each moon.
To calculate the
area
of a
sphere
using a program, you should
first
write
the program, then you must
record
the program into
the calculator, and finally you
run
the program to calculate
the answer.
Writing the Program: You have already written it! A program is
nothing more than the series of keystrokes
you
would
execute
to
solve
the
same
problem manually.
Recording the Program: To record the keystrokes of the pro-
gram into the calculator:
I.
Slide the PRGM-RUN switch
PRGM~RUN
to
PRGM
(program).

record-
ing a program, the display gives you information that
you

,
but you
can
ignore the display for
now.)

These
keys are the same keys you pressed
